Hello. Is there any way to control the px-360 without the touch screen. Mine is cracked and does not detect anything. I mostly use it as a digital piano, so that's fine. But I was just wondering if there are any combination of keys to change sensibilty or tone, like what I had on my CGP100. Or maybe over the midi usb? Although I doubt it. Thanks in advance. PS. Anyone knoe where I could get the digitizer? I have found the whole lcd assembly for almost $400, but I only need the digitizer.
